Important Questions on Atoms, Molecules and Nuclei
Assertion: Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. Reason: For heavy nuclei, the binding energy per nucleon increases with increasing while for light nuclei it decreases with increasing .

An electron in the ground state of a hydrogen atom is revolving in anticlockwise direction in the circular orbit of radius . The atom is placed in a uniform magnetic induction such that the plane normal of the electron orbit makes an angle with the magnetic induction. The torque experienced by the electron is,
